Angiosarcoma and Vascular Surgery: A Case Report and Review of Literature.

INTRODUCTION: Angiosarcomas (AS) are rare and aggressive neoplasms originating from the endothelium: they represent less than 2% of all soft tissue sarcomas and usually have a poor prognosis. Although more often primary, different risk factors have been described and some cases are associated with vascular surgery. Materials and Methods: We present the case of an 84-year-old man who developed an AS on his thigh 3 years after a popliteal bypass with autologous saphenous vein. We performed a thorough review of the literature describing the main characteristics of the 25 cases (including ours) of AS associated with vascular surgery reported from 1981 to 2022. Results: Most of the patients were males (21 men vs 4 women) with a range age of 50-84 years. Most of AS are associated with Dacron grafts (12 cases), the overall mean time to onset is 7.8 years after surgery. The most common presenting symptoms are pain (20 cases) and weight loss (10 cases), while cutaneous presentation is uncommon; indeed, violaceous and painful papules, plaques, nodules, and skin ulceration have been found in 3 cases only. Due to unspecific symptoms, differential diagnosis is often difficult and a biopsy for histological confirmation is mandatory. Conclusion: Even if it seems to be a very rare complication, AS should always be considered in patients with compatible symptoms and who have undergone vascular surgery in the past.

Acral perineurioma: A case report of a rare neoplasm successfully treated with autologous skin graft reconstructive surgery.

Soft tissues perineurioma is a rare nerve sheath tumor that affects most of all the subcutaneous tissue. Even if it could present as a large mass, it is a benign neoplasm for which a complete surgical excision represents the gold standard treatment. Considering that it usually affects acral sites of young people, it can be challenging to perform a reconstructive surgery that allows a full functional recovery. We report the case of a woman in her 20s presenting a perineurioma of the sole of the right foot, a nodule of about 2 cm of diameter that compromised the support of the foot on the ground. We performed a radical surgical excision with no recurrence after 3 years of follow up and we obtained a full functional recovery thanks to an autologous full-thickness skin graft.

Keratolysis exfoliativa-like eruption induced by ranolazine.

Dermatoses affecting palms may represent a dermatologic challenge from both the diagnostic, and therapeutic point of view. Patients with supposedly occupational dermatitis can spend months or even years in a frustrating attempt to avoid contact with possible irritants or allergens. To underline the importance of a thorough unbiased analysis of the patient's history and clinical features, we present the iconic case of a bricklayer affected by a chronic, disabling desquamation of palms which in the end was classified as keratolysis exfoliativa (KE) attributed to ranolazine-intake, an antianginal drug. To the best of our knowledge, this specific adverse effect of druginduced KE of palms has never been reported before in association with ranolazine.
